Dear Robin,
Hi Igor,
Did you meet any issue with my latest patch?
sorry, but unfortunately I have no time to test it.
I have switched to PIO mode and continue other development.
Maybe later I will find time to test DMA mode, but not sure when.
Thank you for support!

Dear Robin,
I have made additional tests on another exemplar of board with
absolutely same hardware.
The spidev_test failed on eCSPI2 and eCSPI5 interfaces, but works
successfully on eCSPI1 interface.
So, it looks, issue does not correspond to fixed interface number.
This is generic issue
Dear Robin,
Please apply the attached patch which is based on linux-next commit
05d08e2995cbe6efdb993482ee0d38a77040861a.
Please notice it has already contained two sdma patches revert - "ad0d92d7ba6a" and
"25aaa75df1e6"
1) Yours source code is same as mine with exception of SDMA

Dear Robin Gong,
Sorry...below another sdma patch(ad0d92d7ba6a) need to be reverted,
because spi driver may dynamically change burst length.
now I have reverted patch ad0d92d7ba6a.
Patches 0001-dma-engine-imx-sdma-add-mcu_2_ecspi-script.patch and
0002-spi-spi-imx-fix-ERR009165.patch are

First issue is
[ 4465.008003] spi_master spi0: I/O Error in DMA RX
Second issue is duplication for one of received bytes.
Dear developers,
I have update about these issues.
12 hours testing show very fast (some seconds) appearance of byte
duplication at interface spi4 (alias for ecspi5), while interfaces spi0
(alias for ecspi1) and spi1 (alias for ecspi2) work flawless (at least
without any other OS load).
